摘  要：
以科尔沁沙地典型流动沙丘作为研究对象,通过样方法调查分析了不同地形上掘穴蚁的蚁丘密度、直径、盖度及其与土壤环境的关系,讨论了不同地形和土壤环境对掘穴蚁筑丘活动的影响,并探讨了蚁丘的空间分布格局.结果表明:受到地形变化影响的土壤环境和地形共同影响掘蚁穴的筑巢活动,蚁丘密度表现为丘顶>背风坡>迎风坡;蚁丘直径和盖度均表现为丘顶>迎风坡>背风坡,并且亦均受到蚁丘密度的制约.蚁丘的空间格局表现为随机分布型.地形及土壤环境的共同作用决定了掘穴蚁的筑巢行为.

摘  要：
Taking the typical mobile dune in Horqin sandy land as test object, the density, diameter, and coverage of Formica cunicularia mounds on different land forms were investigated by quadrate method, with the spatial distribution of F. cunicularia mounds and the effects of topography and soil property on F. cunicularia nest-building activities discussed. The results showed that the density of F. cunicularia mounds decreased in the order of ridge>leeward slope>windward slope, while the diameter and coverage of the mounds were in the order of ridge>windward slope>leeward slope and conditioned by mound density. The spatial distribution of F. cunicularia mounds was in random pattern. Topography and soil property co-affected the nest-building activities of F. cunicularia.
